For my regular pairs

[Sandy]

I have made an appointment for tomorrow with an eye place that can fill anything.
I am making a computer + reading pair (see my other post specifically on that) and so this post is for regular pair which if possible, I'd would liek to use as sunglass pair as well with a clip. So,

Q1: I will buy a rimless frame and use high index. Should I get the one or with hinges or without hinges? And what brand would be best for sturdyness? And will have the choice to get the clip for sunglasses? I will use that clip for sunglasses only if that arrangement provides good protection forom sun. i don't midn makign a pair of sunglasses.

Q2: Note that the main reason I am buying rimless is so that I won't be limited in choices with fitting size, for the following RX, what choice of lens will you recommend for PAL? And what AR?

+1.50 -0.75 150
-0.25 -0.50 040 (Add is 150)

Even though I am going to an optician (at a nearby town), I would like to have some ideas to choose from. So please help me.

Thanks.

Can't immagine why you waste the extra money on high index with a miniscule Rx like this. With the henge, you can have screws falling out or loosening, without the hinge they are a pain to put in the case.

Yea, I too think high index is an overkill on this script. Go with Trivex since thickness isn't going to be an issue.

Refers you to my thread about "Ultimate" or "best comprimise"http://www.optiboard.com/forums/showthread.php?t=15022

you dont need to worry about Index as much as you do ABBE value!

Ditto!

Ok, I won't waste money. So I should get the rimless frame with hinge since I like to put it in the case.

I am disappointed with to the place I went to. I drove all the way there 1/12 hour one way because he can get any lens for me.

Once I got there, he is hung up on that pentax brand I know nothing about saying that it's the latest and from Japan and the best and not in the market yet, etc. (I had posted about this brand before and no one has heard of it.) The annoying part is that something I know nothing about and not in the market cost a lot more. What more? Because I don' buy the frame form him, even though he didn't say that that's the reason, he is going to charge me $80 for cuttign the lens. These people don't get that they just won't get the business from me. I am doing the computer lens with him though using my current frame. I'll go to another place with the frame in hand and say I want to resue this frame to see whether they wil charge me that $80 too. If they would, I won't bother as all I really need is Computer pair since I plan to be, officially, a geek:)-

Okay, but I need to work on finding a place that *works* with me.

Thanks for the link. I was wondering about that all along and now that you said it explicitly, I won't be hung up on high index.

the only way i use high index in your RX is in a rimless, to give mechanical stablility, and in that instance I use 1.6 or poly. However the introduction of Trixex has solved that problem... the next issue is what materials are available in the progressive design you need

The point I am making is that we (as profesionalls) need to make a balance. In a rimless, I would be balancing colour distortion against mechanical stability against the progressive lens designs (which are not all available in all the materials). When you throw in AR coats, aspericity, lens forms, frame B measurements, overall heights, fitting charateristics, facial features - you will understand thats why you need a professional that understands all the issues, because, there is a lot more to consider than is obvious immediatally

As a consumer this must seem like a nightmare, because you have to contend with lens sellers, who possibly dont know thier lenses as well as they ought to, and retail outlets (and the organisations behind the outlet) that push lenses for commercial reasons only

There are good practitioners out there, but they are in decline, and becoming harder to find. I would spend some time finding the right one, and stick with them

[QDO1]

I need to put another misconception to bed for you

If we are talking plastic lenses - some lens sellers call high index anything that isnt CR39 n=1.49, others make the split at say 1.6, or 1.67, calling the lenses in between mid-index

We have available in plastic the following refractive indicies:
n= 1.49, 1.53, 1,54, 1.56, 1.59, 1.6, 1.67, 1.71, 1.74 and a few arguable "in-between" lens materials

The blunt reality that each of those lenses have very different qualities in terms of mecanical stability, hardness, colour abberation, reflectance, thinness, required centre thicknesses, and those qualities are not nessacarily related with the refractive index

So when I said in the previous post 1.6, 1.59, or trivex (1.53) are suitable for rimless that is a qualitative comment regarding only mechanical stability, which is not an optical quality

If I understand you correctly you are planning to get one computer pair and one regular progressive with a sunglass clip.

Then you say you will buy a rimless frame(drilled rimless?). Then in a later post you say the optician is going to charge you $80.00 extra to use a frame you already have. Or maybe you are buying it elsewhere?

I do think a extra charge is reasonable if you are bringing your own rimless frame to have lenses put in. Labs do charge extra to do drill mounted glasses. Not every optician will pass that charge on but I can understand doing it.

Several people mentioned Trivex for the rimless frame. Trivex is the perfect material for drilled lenses, but I think only two progressives come in Trivex (please correct me is I am mistaken) the Hoya Wide and the Younger Image. I like the Hoya Wide but I do think there are better progressive choices then these.

I suggest you get a polycarb lenses with a AR for the drilled glasses. Some people like to go on about the lower ABBES on poly, but millions of people wear it very happily. I have worn it with no problems. There are some excellent choices in poly progressives.

Thanks! I have never heard of Excelite X-pro. I didn't know Genesis was available in Trivex. I have heard this is a good progressive, but have never used it.

I have a pair of Summit CDs and I wondered if this was available in Trivex when I was typing my last post. I think it is a poor progressive and don't sell it.
